Web activated telephony, but you control the cost!
 

No VoIP equipment required!

Initiate calls between any two phones, anywhere in the world. No restrictions - either end can be a land line, mobile or VoIP phone. You control the cost of the call by choosing your own providers - there is no lock-in to the service provider. Even choose two different providers for each leg of the call. The possibilities are only limited by your imagination. For more details see our tutorial

From your Web Callback tutorial:

"You also sign up with a provider in another country (eg. USA) that provides untimed local calls for 8c."

Do you happen to know of a USA provider that offers untimed local calls in this manner? I'm simply curious as I've been doing a lot a research on provider costs and plans recently and hadn't run across any with this billing approach.

Thanks.

Ron

More suggestions for your todo list:

Add a clickable Web Callback version of Speed Dial that accepts, stores, and executes Web Callback information. Once set up, frequently called numbers are only a click away.

Also, since most of the time everything in Web Callback but the "Number to Dial" will be the same, these fields should default to user-defined preferences.

Good ideas Ron. The looks like we will be very busy over the next few weeks working on them :)

I was wondering how much premium account will cost? Can you give me an indication. I have got fast internet access, but for those people not willing to pay money(15 euro/month) for internet provider I think this service rocks. But offcourse then premium account should not be to expensive... I got family without fast internet and I am thinking:
a. giving them fast internet.
b. give them premium account

Many thanks,

Hi Alfred,

A premium VoXaLot account will require a small annual fee. We plan to run the Web Callback trial for a couple of months to determine our bandwidth and hosting costs. We will then use these figures to determine the fee.

I can say that based on our current estimates, it will be significantly less than the cost you are paying for your high speed internet.

Martin, just checking that I understand how this works...

Web Callback:

You are actually proxying the media for the VoIP calls (and possibly doing transcoding between codecs for the two "legs" of the call), hence not insignificant bandwidth costs accrue to you, hence the need for a fee.

Sip Broker / Voxalot:

You are only proxying the signalling for the call (once the call is setup, the media passes directly between the call endpoints), and so the only bandwidth costs to you are a couple of UDP packets for SIP messages and DNS (ENUM) lookups.

Hi,

Web Callback - 100% correct as you describe.

SIP Broker, just handshaking and once call is established it is P2P (again as you describe).

VoXaLot, depending on the client NAT settings is a combination of just handshaking and RTP proxied traffic.

Okay, thanx Martin. Please keep me informed :D

Keep it simple
 

A feature that I would like is a *really* simple web interface. No frames, no graphics, no nothing. Purpose is to allow one to use a mobile phone browser (or a Blackberry browser) to initiate the callback. To go with this, a default "calling from" number should be setup so that all you have to enter is the number you want to call.
